When deleting a user, if its home directory does not belong to it, it should
not be removed. This is the promise that the manpage makes, the tool should
ensure that it respects that promise.

Instead of using pw to modify group membership, users often edit
/etc/group by hand, which is discouraged. Provide an example of
adding a user to the wheel group, which is a common use case.
I'm using a different user here as in the previous example as that
deleted the user (although the examples don't necessarily have to
be followed in order).

It was also leading to segfaults; pw can be NULL when control reaches these

pw_scan(3) has been fixed in a way that doesn't perturb other callers of
it or the getpwnam(3) family.
Make pw(8) showuser work the same with or without -R <path> for non-root
users. Without -R, pw(8) uses getpwnam(3), which will open master.passwd
for the root user or passwd for non-root users. With -R <path> pw(8) was
always opening <path>/master.passwd, which would fail for a non-root user,
then falsely claim the userid you're trying to show doesn't exist.
Now for a non-root user it opens <path>/passwd, and populates the fields in
the returned struct passwd which aren't present in that file with well-known
canonical values, which duplicates the behavior of getpwnam(3). The net
effect is that the showuser output is identical whether using -R or not.

Two PRs (152084 & 210187) request allowing the "@" and/or "!"
characters in the passwd file GECOS field. The man page for pw does
not mention that those characters are disallowed, Linux supports those
characters in this field, and the "@" character in particular would be
useful for storing email addresses in that field.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
No functional change intended.
Previouly it was possible to create users with spaces in the name with:
pw useradd -u 1234 -g 1234 -n 'test user'
The "-g 1234" is relevant, without it the name was already rejected
as expected:
[fk@test ~]$ sudo pw useradd -u 1234 -n 'test user'
pw: invalid character ` ' at position 4 in userid/group name
Bug unintentionally found with a salt config without explicit name entry:
test user:
user.present:
- uid: 1234
- gid: 1234
- fullname: Test user
- shell: /usr/local/bin/bash
- home: /home/test
- groups:
- wheel
- salt
"Luckily" salt modules rarely bother with input validation either ...

"pw usermod someuser -G ''" is supposed make sure that someuser
doesn't have any secondary group memberships.
Previouly it was a nop because split_groups() only intitialised
"groups" if at least one group was specified. As a result the
existing secondary group memberships were kept.

r285050 fixed a bug in pw that could lead to /etc/passwd or /etc/group
corruption on power loss. However, it fixed it by opening those files with
O_SYNC, which is very slow, especially on ZFS. This change replaces O_SYNC
with appropriately placed fsync()s instead, which is much faster. Using a
ZFS tmpdir, the time to run pw's kyua tests drops from 245s to 35s.

Just like with freelocale(3), I haven't been able to find any piece of
code that actually makes use of this function's return value, both in
base and in ports. The reason for this is that FreeBSD seems to be the
only operating system to have such a prototype. This is why I'm deciding
to not use symbol versioning for this.
It does seem that the pw(8) utility depends on the function's typing and
already had a switch in place to toggle between the FreeBSD and POSIX
variant of this function. Clean this up by always expecting the POSIX
variant.
There is also a single port that has a couple of local declarations of
setgrent(3) that need to be patched up. This is in the process of being
fixed.

The length of the name returned from the $LOGNAME and $USER can be
very long and it was being concatenated to a fixed length buffer
with no bounds checking. Fix this problem by limiting the length
of the name copied.
Additionally, this name is actually used to create a format string
to be used in adding log file entries so embedded % characters in
the name could confuse *printf(), and embedded whitespace could
confuse a log file parser. Handle the former by escaping each %
with an additional %, and handle the latter by simply stripping it
out.
Clean up the code by moving the variable declarations to the top
of the function, formatting them to conform with style, and moving
intialization elsewhere.
Reduce code indentation by returning early in a couple of places.

Summary of changes:
- Replace all instances of FILES/TESTS with ${PACKAGE}FILES. This ensures that
namespacing is kept with FILES appropriately, and that this shouldn't need
to be repeated if the namespace changes -- only the definition of PACKAGE
needs to be changed
- Allow PACKAGE to be overridden by callers instead of forcing it to always be
`tests`. In the event we get to the point where things can be split up
enough in the base system, it would make more sense to group the tests
with the blocks they're a part of, e.g. byacc with byacc-tests, etc
- Remove PACKAGE definitions where possible, i.e. where FILES wasn't used
previously.
- Remove unnecessary TESTSPACKAGE definitions; this has been elided into
bsd.tests.mk
- Remove unnecessary BINDIRs used previously with ${PACKAGE}FILES;
${PACKAGE}FILESDIR is now automatically defined in bsd.test.mk.
- Fix installation of files under data/ subdirectories in lib/libc/tests/hash
and lib/libc/tests/net/getaddrinfo
- Remove unnecessary .include <bsd.own.mk>s (some opportunistic cleanup)
Document the proposed changes in share/examples/tests/tests/... via examples
so it's clear that ${PACKAGES}FILES is the suggested way forward in terms of
replacing FILES. share/mk/bsd.README didn't seem like the appropriate method
of communicating that info.
